In the article 7, it says that the consultations and negotiations towards reunification may be conducted in steps and phases and with flexible and varied modalities, which is unique in the usually strict laws in China. The words "in steps and phases", "flexible" and "varied" shows that Chinese Communist Party is willing to negotiate with Taiwan in a large scope, without forcing it followiing a fixed schedule.
Article 7 also said about the six issues in the negotiation, including "officially ending the state of hostility between the two sides", "mapping out the development of cross-Straits relations", "steps and arrangements for peaceful national reunification", "the political status of the Taiwan authorities", "the Taiwan region's room of international operation that is compatible with its status" and other matters concerning the achievement of peaceful national reunification. Though time is limited for Lien to fix all issues in this trip, the three books as presents from KMT to CCP may try to explain KMT's idea in a more vivid way. The books include(in Chinese) a book on Taiwai's history written by Lien's grandfather, another named "Hope only after change" written by lien himself and a new one named "Lien's 2005 trip to mainland". The second one gave a clear idea about Lien and KMT's point towards reunification.
Lien asked for the possibility to re-negotiate shortly after the pass of anti secession law. In March 15, one day after the pass of anti-secession law, Lien said(in Chinese) that Taiwan and mainland must go back to the status of "no independancy, no war" with the gradual solution in the peaceful time from 30 years to 50 years.
Chinese media praised highly on Lien's trip, remaining me wonder if Lien's books will be published in mainland in the near future.
